Unit 4 Review
例如：
the letter says that they are arriving on sunday. 信上說，他們將在星期天到達(dá)。
let’s suppose that one day this happens to you. 讓我們假設(shè)，有一天這事發(fā)生在你身上。
注意：
1.經(jīng)常在及物動詞和賓語從句之間插一個間接賓語（人）。例如：he told me that she was wrong. 他告訴我說，她錯了。
2.在動詞think, believe, suppose, expect等后面的賓語從句中的否定詞經(jīng)常前移。例如：
i don’t think you are right. 我想你是不對的。
i don’t suppose he cares, does he? 我看他不在乎，是吧？
we didn’t believe he had finished his work. 我們相信他還沒做完他的工作。
3.許多帶復(fù)合賓語的句子，that引導(dǎo)的賓語從句經(jīng)常移到句子后部，而用it作形式賓語。例如：
we think it wrong that he told a lie to everyone. 我們認(rèn)為，他對每個人都說了慌是錯的。
he thought it a pity that she missed the chance. 他認(rèn)為，她失去這次機(jī)會很可惜。
溫故而知新：賓語從句
時態(tài)的一致問題
一、主居與從句是否一致應(yīng)視情況而定。 例如：
主 句 從 句
i think that
i will know that
i have heard that
he often does it.
he is doing it.
he has done it.
he will do it.
he has been doing it.
he did it yesterday.
he had done it by that time.
…
二、主、從句一致。例如：
1. he said that he didn’t know me. 他說，他不認(rèn)識我。
2. i didn’t know where she was going. 我不知道，她要去哪里。
3. i told him that i should go at once. 我告訴他，我得馬上走。
4. she forgot what she had learned. 她忘了她所學(xué)的東西。
注意：
1.如果從句所敘述的為真理或不變的事實，則永遠(yuǎn)用現(xiàn)在時。例如：
at that time, people did not know that the earth moves. 當(dāng)時人們還不知道，地球是在運動著。
試比較：
he said he gets up at six every morning.
他說他每天早晨6點起床。（過去有此習(xí)慣，現(xiàn)在沒變。）
he said he got up at six every morning.
他說他每天早晨6點起床。（過去有此習(xí)慣，現(xiàn)在已改變。）
he told me last week that he is eighteen.
他上周告訴我，他18歲。 （不變的事實）
he told me last week that he was sick.
他上周告訴我，他病了。（當(dāng)時的事實）
2.主句動詞無論是什么時態(tài)，賓語從句中的助動詞ought, need, must, dare是不變的。例如：
he thinks / thought that i need not tell you the truth. 他認(rèn)為，我沒有必要告訴你真相。
3.動詞know后面的賓語從句，應(yīng)注意時態(tài)的運用。試比較：
i didn’t know you are in london. (過去不知道,而現(xiàn)在知道)
i don’t know you are in london. (現(xiàn)在不知道)
i didn’t know you were in london. (過去不知道,當(dāng)時在倫敦)
我不知道, 你在倫敦。
猜測might/may/must
問：這一月我學(xué)到很多關(guān)于might / may 的知識，以前我知道m(xù)ay 表示“可以”，而might是may的過去式，可是這學(xué)期他們的意思與用法似乎變了，不再是我以前的may/might了，為什么？能幫幫我更清楚地認(rèn)識一下他們嗎？
答：你真是一個善于觀察的學(xué)生，好吧！看你這么愛學(xué)習(xí)，我不妨就給你講講他們的其他用法，注意看了：
